NATHAN M. LOWER, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR 'IO LOCOMOTIVE STOKER COMPANY, A CORPORATION OF PENNSYLVANIA.

LOCOMOTIVE STOKE-R.

Be it known that I, NATHAN M. LowER, a. cltizen of the United States. and resident of Pittsburgh, county of Allegheny, and State of Pennsylvania,- iave invented certain new and useful Improvements in Locomotive Stoker's. of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part The invention relates to the mechanism for transferring fuel from a locomotive tender to the locomotive; its object being to provide improved .means for flexibly mounting and connecting such mechanism in order to permit the usual relative movements of locomotive and tender in all directions.

The invention consists of a structure in which the fuel conduit, located'under the tender floor, is loosely connected with a section of the conduit mounted on the locomotive cab, in such manner as to have universal movements relative thereto, includ-- ing telescopic action, and being capable of a limited longitudinal movement with reference to the tender whereby it is prevented from complete withdrawal from the conduit section of the locomotive so long as the tender and locomotive are connected together.

\Vhile the invention may be given a great variety of forms a practical embodiment of it is hereinafter described, and is illustrated in the accompanying drawings, in which- Fig. 1 is a detail longitudinal vertical section of a portion of the'locomotive and its cab; and I v Fig. 2 is a detailsection on the line 22 of Fig. 1.

A portion of the frame of a locomotive is shown at 10, and its cab floor at 11. A portion of the framing of the tender is shown at 12, and its body at 13, the floor of the fuel bin of the tender being shown at 14. .The coupling mechanism for connecting the loco motive and tender together is conventionally represented at 15. A conduit for conveying fuel from the tender to the locomotive is shown at 16, and 'as being located, as usual, below the floor of the fuel bin and as carrying a screw conveyor 17 which will be driven by suitable power mechanism.

The-forward end of the conduit' 16 fits loosely within a tubular end 18 of a section 19 of the fuel conduit located upon the loco Specification of Letters Patent. Patented July 25, 1922.

motive. The entering end 20 of the conduit 16 is shaped as a section of a sphere, thereby permitting universal flexure between the .two sections of the fuel conduit, this rounded section being freely slidable within the socket 18 which receives it. The rearward end of the conduit section 16 is movably supported upon the framing of the tender, and, in the instance shown, by means of a pair of rollers 21, 22, running upon tracks 23, 2-1, thereby permitting longitudinal and swaying movements of the conduit.

A stop for limiting the backward movement of the conduit is provided in this instance by upturning the ends of the tracks 23, 24, as shown at 25. When the screw 17 is operated the reaction will force the conduit section 16 backwardly, and hence the rollers 21, 22, are normally in engagement with the stops 25. Any tendency of the forward end of the conduit section 16 to enter too far into the section 19 may be prevented by forming on the section 15a lug 26 for engaging the rearward end of the nipple 18.

I claim as my invention 1. In a locomotive stoker, the combination with a locomotive and tender, a fuel conduit comprising a section fixedly mounted on the locomotive, and a section having a sliding and flexible connection with the first-named section, means for supporting the secondnamed section on the tender and permit ting its longitudinal and lateral movement, and a stop for limiting the backward movement of such section.-

2. In a locomotive Stoker, the combination with a locomotive and tender, a fuel conduit comprising a section fixedly mounted on the locomotive anda section carried by the tend- I er and having its forward end loosely and removably entered in the first-named section, a support for the rear end of the secondnamed section permitting its longitudinal and lateral movement, and a stop limiting the backward movement of such section.

3. In a locomotive stoker,-the combination with a locomotive and tender, a fuel conduit comprising a section fixedly mounted on the locomotive and a. section carried by thetender and having its forward end loosely and removably entered in the first-named section, a roller mounted on the second-named section, a track for such roller longitudinal of the tender, and a stop for limiting the backward movement of such section.

4. In a locomotive stoker, the combination with a locomotive and tender, a fuel conduit comprising a section fixedly mounted on the locomotive and having its rear end in the form of a cylindrical nipple, and a section mounted on the tender and having its forward end shaped as :i section of a sphere and loosely entered into such nipple, a 1on1 gitudinal track on the tender, a roller mounted on the second-named section and moving on the track, and a stop for limiting the backward movementof said section.

5. In a locomotive stoker, in combination, a locomotive, a tender, a fuel conduit'conb prising a section mounted on the locomotive NATHAN M. LOWER.-
